Motor-control IGBTs cut power dissipation by up to 60 percent

El Segundo, Calif.—International Rectifier's IRGB4056x, 4061x, and 4062x 600-volt insulated gate bipolar transistors (IGBTs) can cut power dissipation in motor control inverters by up to 60 percent for applications up to 2.5 kW.

Co-packaged with ultrafast soft recovery diodes, these IGBTs have lower collector-to-emitter saturation voltage (VCE(ON)) and total switching energy (ETS) than punch-through (PT) and non-punch-through (NPT) type IGBTs. The combination of low VCE(ON) and ETS of the trench IGBTs result in reduced power dissipation and higher power density in motion control applications having a wide range of switching frequency conditions (air conditioner and refrigerator compressors, vacuum cleaners, washing machines, dishwashers, ventilation fans, industrial drives, and circulating pumps).

The trench IGBTs, part of the company's iMOTION integrated design platform, can deliver up to 60 percent higher RMS current in the same package compared to previous devices on the market, according to the company. Their lower power dissipation can reduce the size of the heatsink by as much as 50 percent.
